Question

my question is why photons are weightless and how they will help for time travel

Answer 1

Photons are massless because these are very fast light packets in universe.....

If photons have mass then they can't move faster...coz gravity affect the mass...


It also help in time travel ...because Light effects the time at large perspectives.....

According to Theory of Relativity. :-

Time is not same for all ..., if you are having some motion ...and mass ....you can effect time...
I think that everyone effect time whether it is human being. , an ant or the Stars.....

Albert Einstein once said..

"For us believing physicists, Time is not absolute
.....its just an stubborn illusion....there is no past , present and future....for light....it only present..."
